TO ALL WHOM IT MAY CONGERNz' Be it known that I, IRA MANNING, oi the city and county of Philadelphia, and State of Pennsylvania, haveA invented a new and improved Machine by which the Soles of Boots and Shoes are Channelled and' Bevelled at one and the same operation; andI do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference markedA thereon.

My invention has reference to channelling and bevelling the soles of boots and slices and other leather workat one and the same operation, which is eifected by a tool or machine in which the knives are capable of adjusting, so as to properly gauge the depth and inclination of the channel, and give the required bevel to the edge of the sole. In case the bevel be not Wanted, the bcvelling-knife can be removed by turning Vit on its' centre. nA reference to the accompanying drawing making part of this specification- Figure 1 is a side elevation,4

Figure 2 is also a side elevation, showingpthe circular arm ll.

Figure A3 isa sidco'iew ofthe column A, showing the roller B, the adjusting-plate' C, andthe guide e.

Figure 4 is a front view ofthe same.

Figure 5 is a plan View of the cutter-head n, presser-roller m, and the barrel I.

-Figure 6 is a plan View of the bevelling-knife bed E, and the are Gr; and

Figure 7 is a sectional view of the cutter-head n and the presser-roller m.

Similar letters'refer to similar parts in the several views.

A is a column or stand,to the front of' which an adjusting-plate, C, carrying the frictiomroller B, is attached bythe bolt a, which is contained in a slot in the said'plate, permitting it to raise and lower when thebolt is slackcned. D is a bed or knife-plate, rotating on a hub, 7c, iixcd to its edge, which takes into a corresponding opening in the extension F of the stand.` A. screw, 6, serving for a centre, keeps it in place. The bev-elling-knife E is xedto the plate D by bolts, which, by taking into the slots formed-in it, permit it to be adjusted in the direction of its length. G is a slotted are fixed to the back of the stand, adjacent to the plate, so that its tightening bolt e taksinto the slet. The end of the vibrating plate D is raised or lowered until the knife acquires the requisite inclination relative .to the solo for giving the proper bevel. By loosening the holding-down bolts the knife can be adjusted in the direction of. its length, for bcvelling soles of all thicknesses, H is a curved arm, fixed to the side of the column; its endf extends beyond and above the roller 4B. slot is formed in its end g, so that the distance of the endf'from the stand can be regulated. I is a barrel, ixed to the endf of the arm H, by a bolt, r, passing through a slot in it. By means of thesaid bolt and slot its position relative to the roller B is adjusted. The barrel carries the channelling-knife, and regulates the inclination and depth ofthe channel made by it, and is constructed substantially as follows: j is a spindle contained in the said barrel; it is reduced .in diameter at a point near the lower end of thebarrel, forming a shoulder. The upper end ofthe reduced pora tion' has a screwcut on it, on which take the nuts Z: c.` A spiral spring, J, takes over the spindle between its shoulder and the Ascrew-stopper Z. L is a lifting lever, fixed to the larger diameter ofthe spindle by the bolt m, which moves in the opening formed for that purpose in the side of the barreli Upon the lower end ofthe spindle j, which is fiattened, isV a presser-roller, n, and 'a knife-head or holder, 0, which are constructed and arranged as follows, Iig. 7: o is acircular iat plate, on 'a hub,p, fixed to the attened'portion of the spindle; A Wedge-y shapcd groove is cut in its face,v for containing the channelling-knii'e r, which retains its place by means of' a bolt, s, passing through a'slot in it, for adjusting it. 'It is a presser-roller7 encircling the plate o, and revolves freely on its hub p. An additional barrel, M, for channelling the outside of soles, which requires that the channel be formed at an inclination contrary to that made by the barrel I, is attached to the arm H, as shown. It is precisely similar tothe barrel I in its construction and operation, with the exception that the knitehe'ad and presserroller are dispensed with, the knife being bolted directly to the spindle. A. curved guide, e, as shown, is fixed tothe adjusting-plateG; it projects above the roller B, and extends to the vertical plane of its diameter, terminating abruptly pit is for guiding a sole while being channelled and bevclledi at itsinwardlycurving edges. Y

,To channel and bevel a'sole, adjust the spindle j by the nuts c 7c', so that the presser-roller M bears upon the sole upon the friction-rcl1er B, the barrel I having been previously set to the required inclination. Regulate the knife r, making the distance from its point to the rim of the presser-roller equal tothe depth oi the required channel, and set the bevelling-knife E at the required angle, by depressing or elevating the knife-plete. Pross the sole forward' against the knives, keeping its edge firmly against the guide e, and upon the frictionroller B, which revolves in the direction in which it' moves, thereby reducing the friction. As the sole moves against the knives, they channel and bevel it et one andthe seme time. Particular attention must be given to the inwardly-curvingparts of the sole, which require to be skillfully manipulated. Whenv the knives have traversed the enti-re edge of the sole, the chennelling-knife is cleared, by rota-ting the lever L until its swell takes on the projection u ofthe barrel, which causes the spindle to take into the barrel, when the solo cnn be rcn'iov'ed' i There are two nuts 7c 7c on the s indle as shown; one is :1 lam-nut, which can reedil f be dis ensed with it P J .l 4 5 P a being merely to prevent its attendent adjusting-nut from turning.l

What I claim as my invention, and desire to secure by Letters Patent, is.-

1. The combination and arrangement of n channelling-knife and a bevelling-knife in the same machine, whereby e sole is chennelled and bevelled et the seme time, as shown.

- 2. Arranging the ehennclling and bevelling-knives so that either can be removed, whereby n. solo can either be chunnelled or bevelled, as shown. i

3. The barrel I, wbenconstructed, arranged, and epereting substantially as shown and'described.

4. The adjusting-plete C', the friction-roller B, und the guide a, :is shown'end described.

5. The knife-holder D and the are G, as shown and described. Y

Inl testimony whereof I hereunto sign my nenne to thisspecicntion in presence of two subscribingWitnesses.
